<\/figure>\n\n\n\nEnsayo de corrosi\u00f3n por niebla salina. El ensayo de niebla salina eval\u00faa el comportamiento anticorrosivo de los recubrimientos galvanizados por inmersi\u00f3n en caliente o de zinc-aluminio. Los proyectos costeros suelen requerir m\u00e1s de 1.000 horas de ensayo de niebla salina neutra. El espesor y la uniformidad del recubrimiento se indicar\u00e1n en el certificado de materiales (MTC) y en los certificados de ensayo.<\/p>\n\n\n\n
Ensayos de propiedades mec\u00e1nicas: Se realizan ensayos de tracci\u00f3n y flexi\u00f3n en vigas y pilares de acero para comprobar el l\u00edmite el\u00e1stico, la resistencia a la tracci\u00f3n y el alargamiento. El acero que no cumple los requisitos puede romperse de forma fr\u00e1gil ante un impacto y perder su capacidad de absorci\u00f3n de energ\u00eda, lo cual es obligatorio para proyectos en Europa, Am\u00e9rica, el Sudeste Asi\u00e1tico y Oriente Medio.<\/p>\n\n\n\n Inspecci\u00f3n de tolerancias dimensionales: se aplican tolerancias estrictas al ancho de las vigas, la profundidad de las ondulaciones, el espesor de las chapas, el perfil de los montantes y la separaci\u00f3n entre orificios. Los errores dimensionales excesivos provocan problemas de montaje en la obra y debilitan toda la estructura en caso de impacto. Realizamos ensayos de muestras y proporcionamos el certificado de material (MTC) y la documentaci\u00f3n de ensayo completos para cumplir con los requisitos de las licitaciones en todo el mundo.<\/p>","protected":false},"excerpt":{"rendered":" Test reports are essential for bidding on overseas road infrastructure projects.
